If it doesn't resolve the issue then follow these steps:
Import the correct server certificate (JKS) into the SEPM.
1.Login to the SEPM 2.Click the Admin button - Select Servers and click on the server name (under Local Site) 3.Under Tasks - Click Manage Server Certificate 4.Choose "Update the server certificate" - choose the certificate type (.JKS) - Locate and select the correct .JKS file to restore. (Note: The password is the same for both password fields and can be found next to the KeyStorePass= line in the corresponding .xml file to the .JKS you are restoring from. Typically under %Program Files%\Symantec\Symantec Endpoint Protection Manager\Sever Private Key Backup\ or in the location where you keep them.)
Once the certificate has been restored, restart the SEPM service for the changes to take effect. As the clients check in they will start to communicate with the SEPM successfully.
